Heat Exchanger Flow Configuration Analyzer (Counter-Flow vs Parallel-Flow) Calculator Process & Field Engineering Reference

Engineering Process Reference: Heat Exchanger Flow Configuration Analyzer (Counter-Flow vs Parallel-Flow) Calculator governing plant layout conforming to Incropera & DeWitt Heat and Mass Transfer / TEMA Standards / Kays & London.

1. Engineering Principles & Mathematical Formulation

Rigorous thermodynamic comparison between Counter-Flow (Counter-Current) and Parallel-Flow (Co-Current) heat exchanger configurations. Evaluates Log Mean Temperature Difference (LMTD), required heat transfer surface areas, area penalty ratios (A_parallel / A_counter), thermal effectiveness (ε-NTU), and thermodynamic feasibility limits (such as temperature cross).

This calculation engine executes rigorous mass-balance and hydraulic equations. Every parameter is cross-checked to ensure zero rounding drift across bidirectional US Imperial and SI Metric unit systems.
